gallery at the beginning of the trench, at the western end of the lower drift, 
so as to leave enough space for a waste-heap. That gallery ought to be driven 
300 m under the mountain, which could be thus prospected at a great depth. 
E) Mine MasDsiu 
The manganese mine of La Dsiu lies at 900 m SW from the former 
mine, on the eastern side of the trench Valea Koltojuluj, or Valea Szkerta- 
nyeszkuluj, on the slope of Mount Dsiu, 518 m high. The mine lies 540 m 
above sea-level, it is in reality only a great ditch, in which one can see, on 
the eastern and western walls, a nice manganese-bearing lode. That lode is 
2 m thick of which 1 m is pure ore, and the other meter is ore mixed witb 
guartz and melaphyre. The lode strikes S5W—NE, more exactly 4" 59. Its dip 
is 707 NW. The same lode, towards the SW, crops out again in the trench 
about 30 m lover. A rational prospecting plan should thus be followed. In 
the Valea Szkertanyeszkuluj, there should be driven a gallery 150 m long 
and with a strike towards 4"59 that is, from SW to NE. One should also 
prospect the lode with a little rise of 30 m. That gallery would show us 
whether the lode is worth working at the level of 30 m. Along that level, 
one could put up some rises. (See plan Fig. 45.) 
I the ore of that outcrop, Mr. K. Emszr found 293290 Mn0O,, that is 
215190 of Mn. Mr. Szizrágyi, in another sample, taken from the mine, found 
62:1690 of Mn0O,, that is 4890 metalic manganese. 
The visible part of the lode is about 60 m long and 8 m high, verti- 
cally. If we take 1 meter for its width, the guantity of ore will be 480 m8, 
that is, with a specific weight of 2-5, a tonnage of 1200 tons of ore, yielding 
from 40 to 5090 of manganese. . 
After the prospecting work is finished, it is possible that the guantity 
will be greatly increased. 
F) The manganese ore of the Mine cHopes. 
This place, which is also called outerop of the Brook Bojlor, lies one 
kilometer NW of the church of Godinesd, under the mount Bojuluj which is 
460 m high, and lies in the trench Pareubojlor which has an eastern direction. 
The gallery was driven at 400 m above sea-level. The lode strikes towards 
17"109 that is about EW and dips 859 N. 
The lode is visible on a vertical height of 15 m. Its width varies from 
08 to 12 m. The filling of the upper part of the lode is a brown melaphyre- 
tuff, impregnated with manganese. 
In the depth, the manganese becomes purer. Towards the east, the lode 
has been prospected by a trench; at 100 m W of that point, and about 30 m 
higher, there has been a trench dug which has given out manganese of good 
guality. It is therefore towards that point that one has to direct the pro- 
specting:
